Happy Birthday, David Dunlap Observatory!
Home to the largest optical telescope in Canada, the David Dunlap Observatory represents a unique place in Canadian scientific history.
Since 2009, the DDO has been operated by the Royal Astronomical Society of Canada, Toronto Centre as an education and public outreach facility. A long-time registered charity, the Toronto Centre of RASC has now been been given the observatory and adjacent administration building. We're grateful for the honour and will continue to honour the spirit of the Dunlap family's legacy.
The University of Toronto has in recent years returned historic books, furniture and many artifacts to RASC’s care, making a visit to the Observatory a unique experience.
When we celebrated the DDO's 80th anniversary on June 13 and 14 there were even more extraordinary moments.

Past Observatory Directors and University of Toronto faculty and staff joined us to celebrate 80 years of stargazing. We also welcomed hundreds of Richmond Hill residents to an Open House.
The David Dunlap Observatory is located at 123 Hillsview Drive, off Bayview Avenue north of 16th Avenue in Richmond Hill, Ontario.
Throughout our regular season, join us for an evening of telescope observing, space crafts, space talks and tours. On program nights we check out a wide variety of celestial objects, including the Moon, Jupiter, Mars, Saturn and more. Go to our "Schedule & Tickets" PAGE to purchase tickets for our programs.
